Embodiment 1

[0034] Take 40kg of waste soot and extract it with 280L of water at 40°C for 1 hour, filter, concentrate the extract to a density of 1.2g / mL, take 10,000g of water-extracted concentrate, and add it to 10kg of reconstituted tobacco leaf substrate as a control sample group.

Embodiment 2

[0036] Take 40kg of waste soot, stir and extract with 200L water at 50°C for 1 hour, filter, concentrate the extract to a density of 1.2g / mL, and extract the concentrated solution with water for later use; 2 Carry out extraction, extraction condition is that extraction pot pressure is 25MPa, and extraction temperature is 40 ℃, CO 2 The flow rate is 200L / hour, the extraction time is 4 hours; the pressure of the separation tank is 5 MPa, the separation temperature is 45°C, and 115g of extract is obtained after extraction; 2 Extract 30 g, mix the two evenly and add to 10 kg of reconstituted tobacco leaf base sheet. Through sensory evaluation, compared with the control sample group, the aroma texture and aroma volume are improved, and the flue-cured tobacco aroma is clearer, more Be natural. The irritation and cleanliness are slightly reduced, and the moisturizing feeling remains good.

Embodiment 3

[0038] Take 40kg of waste soot, stir and extract with 200L water at 40°C for 1 hour, extract twice, filter, concentrate the extract to a density of 1.1g / mL, and extract the concentrated solution with water for later use; take 6kg of waste and soot with supercritical CO 2 Carry out extraction, extraction condition is that extraction pot pressure is 20MPa, and extraction temperature is 35 ℃, CO 2 The flow rate is 180L / hour, the extraction time is 3 hours; the pressure of the separation tank is 5.5 MPa, the separation temperature is 40°C, and 265g of extract is obtained after extraction; 2 Extract 20 g, mix the two evenly and add them to 10 kg of reconstituted tobacco leaf base sheet. Through sensory evaluation, compared with the control sample group, the aroma texture and aroma volume have improved compared with the control sample group, and the smoke aroma is more transparent and full Some, the sweetness is somewhat apparent, and the degree of stimulation and cleanliness is sli...

Abstract

The invention relates to a method for extracting a tobacco aroma substance from tobacco raw materials in a directional and combined manner by using a water extraction method and a supercritical CO2 extraction method. The method comprises the steps of (1) directionally extracting a polar aroma substance from tobacco by the water extraction method; (2) directionally extracting a nonpolar aroma substance from the tobacco by the supercritical CO2 extraction method; (3) mixing the polar aroma substance and the nonpolar aroma substance, wherein the proportioning ratio of the polar aroma substance to the nonpolar aroma substance is 1000: (0.1-5). According to the method, the used tobacco raw materials are tobacco leaves, cut tobaccos or wastes, such as tobacco powder, tobacco ash or tobacco stems of tiny grains, generated during tobacco processing, so that the waste is changed into the valuable, and the pollution to the environment is reduced; a water extraction tobacco concentrate and a supercritical CO2 tobacco extract are mixed in an appropriate ratio, and a composite aroma material is sprayed to reconstituted tobacco, so that the quality of the reconstituted tobacco is improved, the aroma amount is increased, the aroma charm is improved, the natural tobacco aroma is set off, the smoke dryness is lowered, the smoke-induced saliva secretion feeling is enhanced, and the degree of comfort of cigarette is increased.

Description

technical field [0001] The invention relates to the field of tobacco, in particular to a method for directional compound extraction of endogenous tobacco aroma substances. Background technique [0002] There are many chemical constituents in tobacco. Since the 1970s, due to the development of analytical testing techniques, chemical components in tobacco have been continuously discovered. Shi Hongzhi et al. reported in 2011 that there were 4,992 identified chemical components in tobacco leaves, of which more than 700 were related to tobacco aroma. The molecules of aromatizing substances in tobacco contain specific aromatizing functional groups such as -OH, -CO, -NH and -SH, which can produce different aromas with different stimuli to the sense of smell. According to the different functional groups of aroma substances, tobacco aroma substances can be divided into alcohols, acids, ketones, esters and terpenes. Tobacco aroma substances are mostly secondary metabolites, so the...
